In
quality of service
, RUDP implements features that are similar to TCP with less overhead.
Implementations
In order to ensure quality, it extends UDP by means of adding the following features:
- Acknowledgment of received packets
- Windowing and flow control
- Retransmission of lost packets
- Over buffering (Faster than real-time streaming)
RUDP is not currently a formal standard, however it was described in an
IETF Internet Draft in 1999.[1]
It has not been proposed for standardization.

signaling.
- RUDP v0 (no checksums) is used for SS7 MTP3 backhaul.
- RUDP v1 (with checksum) is used for ISDN PRI backhaul.
The versions are mutually incompatible and differ slightly from the IETF draft.[citation needed] The structure of the Cisco Session Manager used on top of RUDP is also different.
Microsoft R-UDP
Microsoft introduced another protocol which it named R-UDP and used it in its MediaRoom product (now owned by Ericsson) for IPTV service delivery over multicast networks. This is a proprietary protocol and very little is known about its operation. It is not thought to be based on the above referenced IETF draft.[2]
